TIRE-PLUG.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed June 17, 1914. Serial N 0. 845,668;

To all whom it may concern Be it known that I, LLOYD V. R001), a citizen of the United States, residing at Marietta, in the'county of Washington and State of Ohio, have invented a new and useful Tire-Plug, of which the following is a specification.

he present invention appertains to tire plugs, and aims to provide a novel and improved device for plugging or stopping up pneumatic tire.

The present invention contemplates the provision of a tire plug of unique construction, and embodying a novel assemblage of component parts, to enhance the utility thereof, and whereby the plug maybereadily and effectively applied to a pneumatic tire, and will serve its purposes in an efiicient'manner without the liability of cutting or otherwi'seinjuring the tire, or becoming broken or impaired in its use. 7

It is also within the scope of the inven tion, to providea tire plug of comparatively simple and inexpensive construction, and which will be simple, convenient, practical, serviceable, and efficient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changesin the precise embodiment of the invention herein disclosed, can be made Within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in'its preferred embodiments in the accompanying drawing, wherein:-

Figure l is a perspective view of one form of plug, with the parts separated. Fig. 2. is a sectional view of the plug as applied to the tire for closing or stoppmg'up the puncture. Fig. 3 is a view similar to Fig. 1, of another form of the invention. Fig. 4 is a view similar to Fig. 2, illustrating the sec ond form in use.

Referring specifically to Figs. 1 and 2, wherein one form of the invention is illustrated, the plug depicted therein, comprises a base or closer 1 of rubber or other suitable pliant and resilient material, which is of mushroom or cup-shaped formation to fit against the inside of a tire. The base or closer 1 has embedded therein, a disk or plate 2 which is concaved similar to the base or closer, and which is disposed between the faces or sides of the base.

threaded metallic stem 3 has its butt end loosely embedded within the base or closer 1 and projects centrally from the concaved face of the base. The butt end of the stem 3 is rotatably mounted within the base 1 and through the reinforcing plate or disk 2, and is provided with collars 4: seating against the opposite faces of the plate or disk 2 to anchor the stem within the base but to enable the stem to be rotated with respect thereto.

A tubular gasket 5 of rubber or other compressible material and of smaller cross sectional area thanthe closer, is disposable or insertible above the stem 3 to seat against the concaved face of the base 1, and the gasket 5 is provided at its outer end or at that end remote from the base 1, with a circular socket or recess 6 surrounding the corresponding end of the bore or opening of the gasket. The gasket is also provided with an annular outturned flange 7 at its outer end and surroundin the socket or counter bore 6, and the periphery of margin of the circular flange 7 is provided with an upturned annular lip or rim 8.

circular nut 9 is adapted to be threaded upon the stem 3, and is adapted to fit snugly within the socket or recess 6 of the gasket, and the nut 9 is provided at its outer end with an outturned annular or circular flange 10 which is s'eatable upon the flange 7 of the gasket within the lip or rim 8. y The stem 3 is formed of bendable or flexi-- ble material, in order that the outer or free end portion of the stem may be bent angularly, as-at 11, to serve as a finger piece or lever for forcibly rotating the stem or screw.

11 use, supposing the parts to be separated, as illustrated in Fig. 1, the base or closer 1, after being properly compressed or doubled, is inserted through the puncture or opening 12 formed in the tire 13, so that the base or closer is disposed upon the interior of the tire. The gasket or plug element 5, which has been slipped upon the stem 3, is then forced inwardly upon the stem into the opening 12 and against the base or closer 1, the flange 7 of the gasket seating upon the tread of the tire. The nut 9 is then threaded upon the stem 3 so that it enters the socket 6 of the gasket and whereby the flange 10 of the nut seats upon the flange 7 of the gasket snugly Within the lip or rim 8. The plug is then made secure, by rotating the stem 3, which may be readily accomplished by bending the free portion of the stem angular-1y, as at 11, and which will cause the nut 9 to be forced inwardly so as to cause the base 1 to seat tightly against the inner surface of the tire, surrounding the opening 12, and to spread out slightly, as seen in Fig. 2, to provide an air-tight joint between the rim ofthebase or closer 1 and the tire. The nut 9 being tightened, will also cause the flange 7 of the gasket and the flange 10 of the nut to seat tightly upon the tread of the tire, and furthermore, the nut 9 and base 1 being drawn toward each other, will cause the gasket 5 to be compressed or bulged within the opening 12, so that the gasket entirely fills up the said opening and seats tightly against V V will serve to hold with the drawings,

the walls thereof. After the plug has been madesecure, the stem 3 is cut off, adjacent the outer face of the nut 9.

During the application of the parts of the plug to the tire, cement may be injected into the puncture the base or closer 1 and gasket will be cemented to the tire, and when the cement has set, will firmly secure the base and gasket to the tire to prevent leakage. It is to be noted in this respect, that the base or closer lbeing of mushroom -or cup-shape, the cement, and when the plug is tightened up, the cement will be forced between the adjacent portions of the base, gasket and tire to thoroughly cement the said parts together. 7

From the foregoing, taken in connection the advantages and ca pabilities of the present invention will be obvious to those versed in the art, attention being called to the fact, however,

- that the present plug is more or less pllable or yieldable, as a whole, to conform to the distortions of the tire in use. The present device is not liable to breakin its use, and will not tendto cut or injure the tire, it being noted that the metallic stem and nut do not-contact with the tire, and are spaced from the tire at all points by rubber or compressible portions.

The form of the-invention illustrated in Figs. 3 and &'is modified in certain details,

but in general has the 'advantages'and fimctions above noted. The modified form 1ntread of the tire.

The knob 9 is so positioned,

that it bears against or fits partially within the outer end of the gasket 5' and holds the gasket in compressed condition within the opening 12 for the purpose above pointed out. The dished or ,mushroom; shaped flange 7 of the gasket seats tightlyupon the tread of the tire, and the knob 9 lies snugly upon the gasket, to hold the plug in place. t It is to be noted that the reinforcing ring 10 prevents the knob-9' from being accidentally drawn through the gasket 5; In this form of the invention, the only me tallic part is the reinforcing ring 10, which is entirely embedded within the gasket, and

which is not-liable 'tOQI'OV8'1Ifl11Il01lS to the This form of the device is From Fig. 4 is it willbe apparent, that y when the modified form of plug is assembled with the tire, the free end portion of the stem 3 may-be cut oif :by severing the knob 9: flushwith the gasket 7' to encu'm'bering "proj ection.
